We are unschooly, with a 7 year old. This year I'm planning to do a lot of visits to the Space and Rocket Center here and build on that with American Girl Luciana books. Since DD is in that "I'm going to be an astronaut" phase, we're focusing on math (workbooks, already bought) and handwriting (so she learn cursive soon and be able to write faster for her scientific observations, need to buy some Handwriting Without Tears stuff I guess) and we've got a Snap Circuit Rover set that I hope will get some good play and interest going.
So I guess just snacks for the outings and Handwriting stuff
